Hi! i got my period June 18th and it ended June 24th. June 31st i had a slip in that lasted a second. ive never had sex, but i was just worried about precm. I took a plan b July 2nd before 72 hours was up. A week after i took the pill, i got some bleeding lasting 4 days which i saw was normal. My period is usually irregular , anywhere from 30-40 days! I got my period August 2nd and it's currently august 6th and my period went from heavy the first 2 days to very light. It usually lasts 6 days and it's only been 4. Should i be worried ? I don't feel any different.
